RISK MATRIX

When working out how to answer the consequence, likelihood and risk score ask the questions:

If something did happen what would the IMPACT be?

and then

Now that we’ve put these controls in place what is the LIKELIHOOD of it happening?

Then look at the convergence to work out the risk score.

 

 

LIKELIHOOD DESCRIPTION

 

LIKELIHOOD

This event may occur only in exceptional circumstances.

Not expected but the event may occur at some time.

The event could occur at some time.

The event will probably occur in most circumstances.

The event is expected to occur or has occurred and is continuing to impact
